ATTACHING THILLS TO VEHICLES.

To all whom it may concern:

Be it known that I, LEMAN C. MINER, of the city of Hartford, county of Hartford, and State of Connecticut, have invented a new and useful Improvement in the Construction of the Shackle and Shaft Head to Connect with the Axle of Carriages; and I do hereby declare that the following is a correct description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in the arangement. of the shackle and shaft connecting with the axles of carriages to render them mute, that is to prevent the unpleasant rattling while in use.

To enabel others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

In the drawing Figure l is a side view when complete; Fig. 2, a central section of the same; Fig. 3, plan view and section showing the bolt, &c.; Fig. 4, the bolt and rubber before being screwed up.

I construct the series of parts belonging to the shackle, clip, shaft head, &c., to form the connection to the axle, in the customary mechanical manner. My improvement does not interfere in the least with the usual arrangement.

The alterations that I make are as follows: In one of the jaws of the clip A, on the inside of the same, I make a cuntersunk beveled recess E, extending from the bolt hole to nearly the outer edge of the jaw. This recess E is to receive the adjustable india rubber, or other elastic and compressible packlng F, as shown on the bolt D, Fig. at, which is composed of a small piece of india rubber tube F, placed on the shank of the bolt D, and shown as it is before being compressed into the recess E by the force of the shoulder of the bolt D, when screwed up tight as shown in Fig. 3F. The bolt hole in this jaw is made much larger as the projection under the head of the bolt, I), which is the same as the thickness of the rubber tubeF, which also is of a proper size necessary to pass over the shank of the bolt up to the said projection.

B is part of the shaft.

C is part of end of the axle.

The utility of my elastic and compressible packing is to cause a constant pressure on the side of the shaft head eye, rendering the same perfectly mute in action, without injury to the free movement of the joints. The economy is also a consideration, the first cost being nearly nominal, and can be replaced by anyone in a few minutes, if it should work or wear loose, which will not be very frequent because there is no lateral pressure or friction to cause it.

hat I claim as my invention and desire to secure by Letters Patent, is I The projection on the bolt D, and the arrangement and insertion, of an elastic and compressible substance in the countersink, of the jaw or awe of the clip A, all in combination, in the manner substantially and for the purpose, as herein set forth and described.
